SAO goes back to its roots and slows the pace down for a more comfortable, immersive experience. Does still suffer from some SAO sins.
Lord El-Melloi II’s Case Files {Rail Zeppelin} Grace Note
A fun (though verbose) Fate/Zero spinoff that channels the vibes of Sherlock Holmes, Hogwarts, and the Fate Universe, with a myriad of cameos from other Fate entries.
Fate/Stay Night: Heaven’s Feel III. Spring Song
Studio ufotable flexes on the entire anime industry again with some of the most gorgeous art and animation, coupled with Yuki Kajiura's perfect soundtrack. Unfortunately, the "rules of magic" gymnastics and overly complicated philosophy was distracting and made it more difficult to immerse as the previous movies.
Demon Slayer the Movie: Mugen Train
As the record holder for best box office performance in Japan and #1 Foreign-language film in the U.S., Mugen Train is a fantastic canon movie that sets itself as the pinnacle of what an anime movie of a series should be.
Demon Slayer: Kimetsu no Yaiba
Demon Slayer is an intense shonen that proves that the genre can stay relevant. With stellar animation, music, and pacing, it lives up to its hype. Most episodes will give you full-body goosebumps, make you cry, or both.
The Garden of Sinners (Kara no Kyoukai)
For having the same writer, composer, and animation studio that brings us Fate/Zero and the Heaven's Feel movies, Garden of Sinners has stellar animation and music for a boring, unconvincing story.
Fate/Stay Night: Heaven’s Feel II. Lost Butterfly
An emotionally brutal piece, this is the best installment in the Fate franchise yet.
Sword Art Online: Ordinal Scale
While not without plot holes and a slapped-together ending, this grounds the series back down to its roots and keeps asking those very relevant questions.
Sword Art Online II (Season 2)
This season goes deeper into the psyche of the characters and explores the concept of Virtual Reality applications, ramifications, while also showing both the benefits and risks of immersing oneself online.
Sword Art Online (Season 1)
A fantastically immersive love-letter to MMORPGs backed with strong emotion that makes a great Gateway Anime. Then it goes sideways for the second arc before picking up the pieces for its second season.
